Jannik Sinner's title defense at the 2025 Shanghai Masters came to an unfortunate end in the third round as the Italian had no option but to retire mid-match after experiencing severe cramping. Sinner headed back to Monaco following his heartbreaking exit from Shanghai, but according to two fans, the Italian is doing alright now and should be able to play again soon.Sinner, who was the second seed at the prestigious ATP Masters 1000 hardcourt event, took to the Qizhong Forest Sports City Arena's Stadium Court on Sunday, October 5, to face No. 27 seed Tallon Griekspoor. The Italian narrowly won the first set 7-6(3), but was pegged back by the Dutchman, who won the second 7-5.In the decisive third set, Jannik Sinner began to cramp and not long after, his situation worsened dramatically, as he was barely able to move. Trailing Griekspoor 2-3, the World No. 2 retired, subsequently needing assistance to make his way out of the court. Sinner flew back to his residence in Monte Carlo, Monaco, shortly after his Shanghai exit.Recently, the owner of a bakery and his wife, who were on vacation in Monte Carlo, ran into Sinner while shopping at a supermarket. The husband and wife both happen to be fans of the Italian.According to the husband, Ginetto, Sinner was gracious to acknowledge the married couple and even took a selfie with them. Ginetto also claimed that the former No. 1 assured them that he's well following his concerning cramping episode at the 2025 Shanghai Masters."Before saying goodbye, we even chatted a little: Jannik told us he's fine now," Ginetto said.
